f To all wl omit concern;

Be it known that 1, WILLIAM Bnimine,

a citizen of the United States, -'residing at S' l geles and State of California, have invented .a new and useful Process'of Treating Hy-- drocarbon Oils, of which the following is a ales," in the county of Los An- ..specification. J

.-This invention 'i'elates 'tothat step, in the treatment of hydrocarbon oils 'which. di-

- rect-lyfollows the neutralizationofthe acid, thepresent invention relating towthe clearing of the ,-oil or removal therefrom of the saponaceous and other byproducts together withwater. 1

" .1--'lh'e main object Hi the present invention is to eifect rembval of the' water-and other impurities in a rapid and economical manner. w

Another ob ect' of the invention 1s.to re-' move the bloom' from hydrocarbon 'oils.

It has been nec ssary in the treatment of hydrocarbon lubricating oils to brighten or clarify them after the removal of the tar.

by acid and the neutralization of the acid by alkali to settle or expose the oil to the at- -mosphere for a'cOns'iderabIe time, .say a uirin 'but a few hours.

month, until the water and othervolatile impurities have been separated vor removed. Y

The-present invention provides for elimination of the water, etc., by'an operation rethe removal of the bloom from any hydrocarbon oil, either lubricating oil or kerosene,

by the same rapid and economical treats -,1nent. t

f i The accompanying drawings illustrate an building 2 for containingthe apparatus for treating oil, said apparatus comprises means for subjecting the oil to the evaporating ace 7 tion of'a currentof'warm air, while the oil circulating the oil in a continuous circuit is in a finely divided condition, means for 'a'nd subjecting it to the aforesaid action at each ,ci'rcuit'and also, if desire finally filtering theoil. 4 Y

between thewall sfofthe ending and the I 'saidpartition wall, a chamber 4 whose floor.-

5 is inclined and is provided with ajdra-in 6 at its lowest portion, thisfloor'constituting' splash deck for the purpose hereinafter set forth. Extending upwardly from this chamber is a tower Shaving openings 9- at its upper end which are regulatable by means of dampers'or'shutters 10, a hood 11 being provided inside the tower for protection ,from the'weather'. Means are provided for elevating or pumping the oil froin th e reservoir ortan tower, said means consisting, for example, of-a pump 13 having an intake pipe 1 1 extending down into the reservoir and an outlet pipe 15 one branch 16 of which extends. nearthe top .tifthe tower where it discharges into a funnel 'or trough -17 having a perforate bottom 18 adapted to discharge the oil ina thin stream, or spray so that the 1 to the'ruppe'r part of this oil will become atomized or broken up in falling through the air in the tower. Means are also provided for producing an upward flow of heated air in-said tower,said means consisting, for example, of a fan or blower Y 19 having its outlet 20 discharginginto chamber 4 and having its intake 21 com municating with an air boX -22 provided with an opening 2-3 adjustable by means of a sliding gate 23 and communicating with the outer air. A heating coil 24 is provided in the air box, supplied with steam or other heating medium from any suitable source. The pump 13 and blower '19 may. be op- 1 erated from any suitable driving means, for

example, by belts125 from a' eountershaft 26 which is driven'from any suitable source of power. Filtering means may also be provided in the same plant said means con sisting, for example, of a stack of filter sections 2'? arranged in a vertical series, a pipe 23 leading from the outlet pipe 15 of the 1 pump 13to the top of this 'series,-and a series of draw-oii pipes 30 being provided from the lower portion of the respective sections 2 1: to a manifold pipe 31 whereby oil may be drawn from any one of the sections.

Valves 32, 33 may also be provided in the pipes 16, 28 aforesaid to enable oil to be di-,:-

rected from the pump 13 to the tower 8 or to the filter, as desired. The drain pipe 6 from the splash deck 5 leads to a well 35 at one end of the oil reservoir 1. The circulating pump 13 draws oil by means of pipe 14 from the portion of said reservoir remote from said well, a partition or Wall 36 being preferably interposed between these two portions of the reservoir with an intercommunicating passage or pipe'37 at the upper part of the reservoir to, allow oil to flow from the said receiving end of the reservoir to the delivering end thereof. I

The process is carried on as follows: Oil

suflicient for a run is-supplied into tank 1,

for example, through an intake 40. The machine being set in operation pump 13 draws oil from the receiving end of the tank 1 andforces it through-pipes 15, 16','-to the a trough 17 at the top of the tower 8. During this operation valve 33 is closed and valve .34c is"opened to allow the'oil'to flow, as stated. The oil falls {from trough 17 through the tower 8 and in ite descent encounters theascending current of air in. said towerwhich isproduced by the blower 19, The

operation of the blower 19 draws air from the inlet opening 23' through the air box Q2 wherein the air is warmed to a suitable temperature, and forces this warm air into pipe 6 leading it back to the well the chamber a whence the warm air passes upwardly through the tower'8. 'As the oil descends through the body of' air in the tower.8 it is broken up by the resistance of the air and the upward movement of the air tends to more effectually break up or atom-- iZe the oil. Each particle or drop of oil is accumulatingin this end of the reservoir eventually flows over into the other end through communication 37 aforesaid, and there is thus established a continuous circu lation, the oil'being subjected to the action {of the warm airat each circuit. By the provision'of the partition 36, between the. two ends of the reservoir 1, the body of oil accumulating in the receiving end, that is to say, the end which receives the oil from the pipe 6, is kept separate from the 'oil in the other. end so that the water or other heavy impurities may settle in. the receiving end and be withdrawn from the well :85, the communicating means 37 being located at the upper portion of the reservoir so that only receiving endipasses over into the delivery end'of the reservoir. In a comparatively short-time, 'say' one day, the entire body of remove any water. or other volatile matter lubricating oils, the-effect is torender the and less liable to smoke in burning. When the entire .body of oilin reservoir 1 has thus beentreated itTmay be drawn Qfi' oil being passed through one or moresectionsof'the filter in series according to the amountof'decoloration required. I I

Suitable filtering material-may be placed within the filter 24: which will, while'purifying the. oils, impart a suitable coloring matter thereto inorder that the finished oils may have any desired color or appearance.
